Dip the HydraCell for approx. 10-15 seconds in any water, this causes a chemical reaction between magnesium and oxygen, inducing an ionic exchange releasing electrons (power), which are then collected by the carbon cathode collector and converted into power.
From new there is a 25+ year shelf life if stored clean and dry. The replaceable HydraCell can be stored prior to first use for 25+ years and is activated instantly to full capacity simply by dipping in water. Once activated the cell will operate continuously under load, requiring only periodic re-hydration.
As many times as you like, although we do recommend you add 5% salt solution (tablespoon of salt in a glass of water, ocean) after the 5th dip onwards. This is required if the power output is down and to maintain same brightness. The HydraCell comes preloaded with salt for easy use, but after multiple dips in fresh water the cell may need to be reintroduced to salt or an electrolyte solution.
No, as oxygen is the fuel if it is submerged eventually the chemical reaction will stop (needs to breathe) also as there’s an absorbent membrane holding the liquid it could swell and cause damage to the cell.
Generally a HydraCell will need to be replaced after more than 300 hours of runtime. If you are experiencing low light or constantly having to dip the Energy Cell, it may need to be replaced.
The replaceable HydraCell can be stored prior to first use for 25+ years and is activated instantly to full capacity simply by dipping in water. Once activated the cell will operate continuously under load, requiring only periodic re-hydration.
In certain conditions the HydraCell will dry out prematurely, especially in warm environments and may need to be dipped in water more frequently.
The answer is ultimately yes. However, the first 4-5 dips can be in fresh water as the fuel cell is preloaded with salt. After this time, you need to switch to salt water. This can be ocean water or table salt in tap water (5% solution). This is approximately 5gms of salt in 95mls of water. Or roughly 50gms of salt and 950mls of water will make 1L of 5% solution.
